Ironically enough, I made this post with the assumption that I end up ridiculed and I am quite happy to be wrong about that. You in depth explanation of the BB makes so much more sense to me than what the common short hand used in day to day language. The BB is the name given to the stage at which proto matter became matter. Gotcha. It went from a simple sub atom existence into the age of atoms. What's the next age? Who knows. Anyways I'm going to jump off of that point right into a little biology. It is my understanding that when you look at the ME events in the fossil record, you notice that simpler life forms have an easier time adapting, and thus adapt to changing conditions much faster than more complex organisms, and that's without mentioning extremophiles. The last remnants of life on earth will be the same ones that saw the beginning. So the big crunch would be all matter breaking down into proto matter. Adjacent to many many many other crunches in the multiverse soup, condenses, and... BOOM! New universe! A finite universe to me would be like living in a video game. A simulation with programmed limits and limits to the program. I'm too much of an atheist, I have a hard time accepting the universe as anything other than infinite. With this model in mind there's no reason that there isn't multiverses within multiverses. That's quantum foam as far as I understand the theory. The symmetry of scale. And if you picture a Venn diagram of the sciences that describes our universe, the white space is quantum inside and outside. And then you can make all kinds of Venn diagrams in the white spaces to describe other universes' sciences, and no 2 have to be alike.

Ok. So what I'm getting is that the common perception of the BB as a singular ultra powerful explosion is wrong and is actually more akin to a sea of densely packed Hydrogen than basically reached critical mass and expanded. Correct? Hopefully I am also correct in understanding that the heat death of the universe is all of that Hydrogen evenly spaced out over all of spacetime. How big is spacetime? Jumping of your point, and the one I made earlier about a foam like multiverse and imagining it as a frothy sea of ever churning bubbles for scale, with the insides being universe and the surface tension between them as the outer edges. I can imagine a bubble forming in that churn. And all of that activity looks like all of the BBs and all of the BCs (big crunch) happening simultaneously. It's the only way I can resolve the universe being infinite but not at the same time. And what happened before time and what happens after. How can the fabric of spacetime be infinite yet have a beginning and an end?

A Hydrogen atom if I remember correctly. Just brings me right back around to symmetry of scale. What do you think the LHC does?

I never mentioned observable universe and it's completely moot to the thought experiment. I was implying from the focal point of the big bang the furthest reaches of the universe, or the shock wave edge, if you will, and pondered what happens outside that sphere.

Hi there to whomever may be reading this. I watch a lot of sci-show and a few Caltech lectures on YouTube and I am very fascinated with the universe and how it works as a whole. I am not in university nor do I have anything beyond a high school level of formal education so please forgive my lack of working knowledge on the mathematical aspect of physics and quantum theory. That being said, I have been meditating as of late and my brain started to wander over to the big picture of our universe and beyond. I found myself imagining what that would look like, and before long I was imagining all sorts of ways that could look. I once watched a lecture on black hole physics and it was briefly mentioned that beyond the universe is a sort of inside out black hole with its own event horizon and whatnot. That got me thinking to what our universe would look like from outside of that perspective and I was imagining adjacent universes of varying shapes and sizes and all of a sudden I was looking at a multiverse. Take time dilation into account and look at the multiverse in this way. With seemingly infinite universes coming into existence and an equal amount popping (aka heat death), wouldn't that look like a churning foamy mess? That sounds like quantum foam to me and fits quite nicely into chaos theory as well and the concept of symmetry of scale. I have also heard mention that the physical conditions to allow intelligent life are huge (understatement). Now, imagine our universe inside the multiverse surrounded by all the other universes, and your guess is as good as mine as to how many of them support life, let alone and that is intelligent. Not all infinites are created equal after all. Maybe unified field theory is thinking on the ultra macro scale, asking what happens in between universes. I bet it's quantum.
